Array and pointer

[vijay s]

hai i have doubt with pointer

char *p ="Hello World"

with this declaration i can able to read the content of each character
e.g. Chr = *(p + 2);

but i can't able to write the character in any position
e.g. *(P + 2) = 'c';

but with array there is no problem....
char p[] = "Hello World"

cani know the reason

A string literal is immutable, so if your pointer points to a character within a string literal, you are not supposed to try and change the value of what the pointer points to.

...no matter what people with archaic compilers, who may or may not come along later, tell you.
